Fuel cell based systems are a promising alternative to batteries in man-portable power generation applications.
An improvement of the power density with respect to the weight of the cell - termed as gravimetric power density in this study - can help in achieving lower manufacturing cost and reducing parasitic power losses, which is particularly important in man-portable applications.
Man Portable Air Defence Systems (ManPADs) have been a favoured anti aircraft weapon since their appearance on the military proliferation scene in the mid 1960s.
MAN Portable Air Defence Systems (MANPADS) have emerged as a major cause of aircraft and helicopter loss.
They include 3,000-8,000 so-called Manpads - Man Portable Air Defence Systems - portable missile systems which are a threat to all types of aircraft, including civilian passenger planes.
And he initially insisted that these weapons were what is known in nonproliferation circles as man-portable air defense systems, or manpads — in other words, shoulder-launched weapons.
In 1833 a London carpenter identified as H. Manning created one of the first, the Manning Portable Cottage, for his son, who was sailing off to make his fortune in Australia.
Yes, because of the perceived risk of an attack using shoulder-launched missiles - known as man-portable air defence systems (MANPADS) - by rebel forces fighting in the Sinai.
The same applies for the far more dangerous question of anti-aircraft missiles, known as "manpads" in the trade (man-portable anti-aircraft defence systems), all of which require experienced handling.
They would be vulnerable to man-portable air defence systems (MANPADs), such as the heat-seeking SA-7, that Colonel Qaddafi has in abundance.
Mr. Spleeters has set up and maintains a map of sightings of man-portable air-defense systems, or Manpads (to use the security world's clunky acronym) in Syria.
